apt update failing with Kubernetes

 

 

Overview

During the build process, you may encounter issues when running the apt update command due to a problem with the signing key for the Kubernetes repository. This can prevent the command from completing successfully, resulting in an error message indicating that the repository is not signed.

Common Error Message

When attempting to run apt update, you might see an error like this:

E: The repository 'https://pkgs.k8s.io/core:/stable:/v1.29/deb InRelease' is not signed.

This error indicates that the system cannot verify the repository's authenticity due to a missing or invalid signing key.

Temporary Solution

To bypass this issue temporarily, you can manually add the signing key for the Kubernetes repository before running apt update. Follow these steps:

  1. Add the Kubernetes Signing Key:

    Execute the following command in your job to download and add the GPG key:

    - run: 
    name: Update Kubernetes Key
    command: curl -fsSL https://pkgs.k8s.io/core:/stable:/v1.29/deb/Release.key | sudo gpg --yes --dearmor -o /usr/share/keyrings/kubernetes-apt-keyring.gpg
  2. Run apt update:

    After successfully adding the key, you can now run:

    - run: 
    name: sudo apt update
    command: sudo apt update

    This should allow the update process to be completed without issues.

Conclusion

While the temporary solution allows you to continue working, it is important to keep your images updated and monitor for official fixes from the CircleCI team. By following these recommendations, you can minimize the impact of this issue and ensure a smoother development process.

If you have further questions or need assistance, please reach out to CircleCI support for additional help.
